What does the Bible say about being spiritual versus carnal?

In 1 Corinthians 3:1-4, the Apostle Paul addresses the church at Corinth, discussing their spiritual immaturity. He describes them as 'carnal' because their actions exhibited envy, strife, and division, indicating they were acting like infants in Christ rather than mature believers. Paul illustrates that spiritual growth involves moving from the 'milk' of basic gospel truths to the 'meat' that reflects deeper understanding and application of these truths. Spiritual maturity requires believers to embody the message of the gospel in their lives, promoting unity rather than division.
